LS500h_OM_OM50F42U_(U) 4
Driving WARNING●
Do not shift the shift position to P while
the vehicle is moving.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.●
Do not shift the shift position to R while
the vehicle is moving forward.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.●
Do not shift the shift position to a driv-
ing position while the vehicle is moving
backward.
Doing so can damage the transmission
and may result in a loss of vehicle con-
trol.●
Changing the shift position to N while
the vehicle is moving will disengage
the hybrid system. Engine braking is
not available with the hybrid system
disengaged.●
Be careful not to change the shift posi-
tion with the accelerator pedal
depressed. Changing the shift posi-
tion to any positions other than P or N
may lead to unexpected rapid acceler-
ation of the vehicle that may cause an
accident and result in death or serious
injury.
After changing the shift position, make
sure to confirm the current shift posi-
tion displayed on the shift position indi-
cator inside the meter.
■
Brake pad wear
If any of the following situations occurs,
have the brake pads visually checked and
replaced by your Lexus dealer as soon as
possible.
●
If the thickness of the brake pads
exceeds the brake pad wear limit when
visually checking all four brake pads
(for the brake pad wear limit, refer to
P.465) ●
If a warning message is displayed on
the multi-information display (only the
right-side pads can be detected)
Rotor damage may result if the pads are
not replaced when needed.
F SPORT models: Moderate levels of the
brake pad and disc wear allow enhanced
braking power. As a result, the discs may
wear more quickly than conventional
brake discs. Therefore, when replacing
the brake pads, Lexus recommends that
you also have the thickness of the discs
measured.
It is dangerous to drive the vehicle when
the wear limits of the brake pads and/or
those of the brake discs are exceeded. ■
When the vehicle is stopped ●
Do not depress the accelerator pedal
unnecessarily.
If the shift position is any position other
than P or N, the vehicle may acceler-
ate suddenly and unexpectedly, caus-
ing an accident. ●
In order to prevent accidents due to
the vehicle rolling away, always keep
depressing the brake pedal while
stopped with the “READY” indicator is
illuminated, and apply the parking
brake as necessary.
●
If the vehicle is stopped on an incline,
in order to prevent accidents caused
by the vehicle rolling forward or back-
ward, always depress the brake pedal
and securely apply the parking brake
as needed.
●
Avoid revving or racing the engine.
Running the engine at high speed
while the vehicle is stopped may cause
the exhaust system to overheat, which
could result in a fire if combustible
material is nearby.
